The high end LED Lights like the GTR's and Morimoto's have to be adjusted properly so as to not have the beam pattern shine up blinding other drivers.

The Lights I pictured in my posting are
NON-ADJUSTABLE.

They install just like a Halogen bulb. Insert into the 3 tabs. Button everything up and you're ready to go. The beam pattern is exactly the same as a Halogen bulb. But alot brighter than a Halogen.

 

They all do. Halogen filaments emit light on an almost 360° arc (there's a tiny shadow from the wire that supports the outer end of the filament) while most lens-less LED emitters cover a ~120° arc. They often emit light beyond that arc, but the intensity falls off quickly. Putting those LEDs on both sides of a metal-core circuit board gets you 2/3 of the way there, but you're still going to have two 60° shadows aligned with the circuit board plane. A 3-sided structure would solve the coverage problem, but creates a new one: the structure would be too big to emulate a halogen filament. Even if you had a miracle cooling solution that let you mount the LED packages edge-to-edge in a triangular prism, they would still be pushed out from the filament location.
No LED retrofit "bulb" will perfectly emulate a halogen bulb, requiring each application's needs be considered individually. A given product's lack of LED rotation just means that product can't be used on applications that need rotation.

 

Quite a lot of people have sensitivity to the blue white spectrum that so many LED replacements use. If you were one of those you would not blow it off, as a "new york minute".
I have really good night vision, the blue whites are uncomfortable and as I have gotten older they hit me harder.. Good grade halogens light correctly and are every bit as good as any sub 400 dollar led conversion. (They make real ones that work! But yea they cost real money.)

 

After I installed LED bulbs, my passenger side had a higher hot spot than the driver side. I flipped the bulb but it was pretty much the same. Took all of 5 minutes to aim the bulb downward.

Before I did the swap, I had marked the hot spot with tape on a wall so I could see the difference with the new bulb.

The LED lights I have on my 2015 Honda Fit are NON ADJUSTABLE!!!!!

The LED lights install just like Sylvania Silverstar Halogen bulbs. They fit right into the 3 tabs of the back of the headlight housing. The LED light pattern is EXACTLY THE SAME AS THE HALOGEN BULBS!!!!!! The LED lights don't impeded drivers going in the opposing direction of traffic.

 

You can adjust the vertical aim on the headlight housing. It's a Phillips or a 10mm driver (I think)

The hot spot changed on one of my bulbs so I adjusted it downward. It's very easy and quick to do

 

The stock factory setting of the headlight housing was perfect for my LED light upgrade. I didn't have to adjust the headlight housing.
